Charge Transfer Dynamics in an Electron-Hole Bilayer Device: Capacitance Oscillations and Hysteretic Behavior
Miranda Leigh Davis, Simon Parolo, Sandro Agostini +3
The capacitance and differential conductance of MBE-grown AlGaAs/GaAs p-i-n diodes are investigated. In these diodes, the p-doped layer, an adjacent intrinsic spacer, and a central…

Strongly interacting 2D electron systems: Evidence for enhanced 1D edge-channel coupling
C. Marty, C. Reichl, S. Parolo +4
We observe nearly vanishing Hall resistances for integer filling factors in a counterflow (CF) experiment on a density balanced 2D bilayer system. Filling factor dependent equilibr…

Josephson-like tunnel resonance and large Coulomb drag in GaAs-based electron-hole bilayers
M. L. Davis, S. Parolo, C. Reichl +2
Bilayers consisting of two-dimensional (2D) electron and hole gases separated by a 10 nm thick AlGaAs barrier are formed by charge accumulation in epitaxially grown GaAs. Both vert…
